android 高版本获取WiFi名称需要授予位置权限：

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
获取权限代码：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
    if (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQ_CODE_FINE_LOCATION);
    }
}
获取权限回调

public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case REQ_CODE_FINE_LOCATION:
            if (grantResults.length > 0 &&
                    grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            } else {
                TMLUtils.showTips(this, getString(R.string.req_location_tips));
            }
            break;
    }
}
